vented certain new and'useful Improvements 1n Stoves and Ran es; and wedo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to stoves and ranges, and more particularly thattype of range in which the oven is elevated some distance above thecombustion chamber,'and gets its The nature of the invention is fullydis closed in the description and claims follow ing, reference being hadto the accompanying drawings, in which- Figure 1 is a front view of adevice em- ,bodyingour invention; Fig. 2 is a central section of thesame. Fig. 3 is a section of the same transverse to Fig. 2, showing alsothe application of the device to a high oven. Fig. I is a view from theunder side, of the gas-burner detached. 7

Referring to Fig. 3, which shows in section an oven and connected partsof a highoven range, the numeral 1 designates the part of the combustionchamber communicating directly with the oven through a vertical fine 2.This fine at its upper end connects with the bottom of the oven 3, theproducts of combustion passing up and around the interior of the oven(the oven proper) and out through the smoke-pipe connection 4i, as indicated by the arrows. As usually constructed the connection of the flue2 with the bottom of the oven is direct, but as herein illustrated thegas-burning apparatus serves as a collar to connect said parts, as wlllmore fully hereinafter appear.

In the present embodiment of the invention, which represents thepreferred construction, the gas-burner 5 is in the form of an oval ring,suitably pierced at 6 for the escape of the burning gas. At each end ofthe oval is a hub 7 tapped for connection with a gas-pipe 8 at eitherend as convenience may require, the other end being suit ably; pluggedat 9, as shown. From the up-'- per side of the hollow ring extends aflange; 10 adapted to be bolted to the bottom of the oven. The sectionof pipe 8 serves also for the admission of air, its expanded end 11-having an adjustable gate 12 for the regulation of the air supply. Intothis enters the gas-jet 13, provided with a suitable cook 14:.

Instead of conneotingthe flue 2-.with a flange at the bottom of the gasring, as

might be done, it is preferred in practice to connect the ring with aseparate collar 15, which fits inside the fine in the usual way, and hasan internal seat 16 to receive an annular flange 17 formed at the bottomside of the ring. The parts are connectedby bolts 18 passing through therespective parts, as shown. I

The location of the gas outlets of the burner is not of the utmostimportance, but in'practice it is preferred to place them below thering, as shown. This does not interfere with the heating action of theburner, while the position of the holes is such as to protect them fromobstruction by falling soot, or the like.

The device is of special value in c0nnec-v erably from that shown,without departing from the gist of the invention, but the typeillustratedis the construction preferred in practice, since it is veryeflicient for gas, and

offers no obstruction to the products of com-' chambustion from theregular combustion her. when the gas is shut 01f.

Though not of primaryimportance, it is Iatented Feb. 15, 1916.;

to be noted that the gas-burner is useful also as a means for keepingthe heat passages of the oven clear of soot, the independent use 1 ofthe gas burner tending to burn out unconsumed carbon accumulating insuch passages. 7

Air to support the combustion of gas might be supplied from thecombustion chamber through suitable air passages therein, but inpractice it is preferred to provide the gas-burner with an air supplyindependent of the otheparts o1 the stove, and in close proximity to theburner. This is done by forming the collar 15 with air passages 19,which may be closed by a door 20 when the gas burner is not in use. Thedoor is preferably mounted. on an inclined door or damper support 21attached to the front of said. collar, and inclosing the openingstherein The opening aiiords a convenient means for lighting the gas, andsupplies an abundance of air for combustion;

Having thus described our invention, We claim:

1. In a stove or range having a combustion-chamber, an oven servedthereby and a connecting fine, a gas-burner conforming to thecross-sectional contour of said flue, and forming. a connecting collarbetween the flue and the oven, presenting no interior 0bstruction to thepassageof the products of combustion from the range, said collar beingrecessed interiorly, with gas-out-lets within said recess and openingdownwardly,

whereby said outlets are protected from fall-f ingsoot, substantially asdescribed.

2. In a stove or range having a COI1'1bIlS.-; tion. chamber, an elevatedoven served thereby,- and. a connectingfiue for the products of 30Copies of this patent may be obtained for .five cents each,,byaddressing the ,Commissioner of Patents,
